Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of optical fiber visible laryngoscope for nasal intubation.
Background technology
In anesthesia, first aid with when concentrating treatment, usually need to carry out tracheal intubation, and adopt respirator to guarantee eupnea.Tracheal intubation refers to inserts tracheal strips by a special endotracheal tube through glottis, and endotracheal intubation can attract for airway patency, ventilation oxygen-supplying, respiratory tract and prevent from inhaling etc. by mistake provide optimum condition.Current tracheal intubation adopts visual intubate usually, namely carries out intubate by visible laryngoscope.The Main Function of visible laryngoscope carries jaw off on being, appears glottis, to facilitate intubate.
Existing visible laryngoscope is generally PVC material, and PVC matter is hard, inflexibility, difficulty when making visible laryngoscope to be inserted glottis, and face must be opened just to be inserted into very greatly by patient; In addition, existing visible laryngoscope adopts one group of illuminator to be reflexed to by inner case in extraneous visible system step by step usually, because each illuminator needs to be set to different angles, make whole visible laryngoscope thickness larger, and, existing visible laryngoscope is normally for oral intubation, namely the groove that can pass through for intubate conduit must be set on visible laryngoscope, during enforcement, intubate conduit and visible laryngoscope are together inserted from oral cavity, thus make the thickness of whole visible laryngoscope must could hold intubate conduit greatlyr.Existing visible laryngoscope thickness is generally 15-20mm, and because the thickness of visible laryngoscope is comparatively large, face also must be opened just to be inserted into very greatly by patient.
In sum, existing visible laryngoscope thickness is large, inflexibility, and face must be opened just to be inserted into very greatly by patient, and for the patient that face cannot magnify, just cannot implement intubate, make the state of an illness of patient can not get effective treatment, patient time serious, also can be caused to suffocate and die.
Utility model content
The technical problems to be solved in the utility model is to provide little, the flexible optical fiber visible laryngoscope for nasal intubation of a kind of thickness.
In order to solve the problems of the technologies described above, this utility model provides following technical scheme: for the optical fiber visible laryngoscope of nasal intubation, comprises optical fiber and flexible steel disc, and the length of steel disc is 300-500mm, and width is 5-15mm, and thickness is 1-2mm; The periphery of steel disc is coated with layer of silica gel, and steel disc is provided with the passage that can pass through for optical fiber vertically; The medial end of optical fiber is connected with the minisize pick-up head be exposed to outside passage, and the distance of minisize pick-up head and steel disc medial end is 0-20mm; The outboard end of optical fiber is connected with the visible system be exposed to outside passage, and the distance of visible system and steel disc outboard end is 0-20mm.
Adopt the optical fiber visible laryngoscope for nasal intubation of technical solutions of the utility model, comprise optical fiber and flexible steel disc, optical fiber is used for transmitting optical signal, steel disc is the carrier of optical fiber, for bearing fiber, steel disc is flexible, thus steel disc can be bent to different shapes according to the different position of patient, so that the steel disc carrying optical fiber is inserted into tracheal strips, avoid patient and must adjust position according to the shape of laryngoscope, alleviate the burden of patient, especially alleviate the burden of the patient of face Zhang Bu great.
The length of steel disc is 300-500mm, this length can meet that steel disc medial end is inserted into tracheal strips, steel disc outboard end extends to outside oral cavity, steel disc width is 10-30mm, thickness is 1-2mm, this numerical value when ensureing that steel disc has some strength and conveniently bends, can also meet and also steel disc can be inserted tracheal strips when patient's face Zhang Bu great; The periphery of steel disc is coated with layer of silica gel, and layer of silica gel matter is soft, nontoxic, and it is coated on steel disc periphery and steel disc can be avoided to stab pipe tissue, plays the effect of a protection pipe tissue; Steel disc is provided with passage vertically, and passage is used for receiving optical fiber, and carries out spacing to optical fiber, thus optical fiber together can be entered in organ with steel disc; The medial end of optical fiber is provided with minisize pick-up head, and minisize pick-up head is used for the imaging of person's windpipe inner case; The distance of minisize pick-up head and steel disc medial end is 0-20mm, thus avoids steel disc insert when medical worker cannot see clearly dark and damage pipe tissue; The outboard end of optical fiber is connected with visible system, and visible system is for showing the imaging of minisize pick-up head, and the distance of visible system and steel disc outboard end is 0-20mm, thus ensures that visible system is positioned at oral external, facilitates medical worker to observe.
Principle of the present utility model is: minisize pick-up head is together inserted into tracheal strips along with steel disc, minisize pick-up head carries out imaging to the inner case of trachea, and be transmitted through the fiber in visible system and show, tracheal intubation is inserted into tracheal strips by nostril, medical worker judges the insertion situation of tracheal intubation according to the display situation on visible system, to ensure that trachea is inserted into suitable position, and then realize accurate treatment.
Because this utility model adopts flexible steel disc, and adopt the optical fiber of small volume to carry out the conduction of imaging signal, such that the thickness of visible laryngoscope is less can be realized; And due to the thickness of visible laryngoscope less, therefore when implementing visual intubate, patient only need make lower lip form a finedraw this utility model can be inserted, solving that patient causes because face being magnified cannot the technical problem of intubate, avoids patient because of cannot intubate and cause the tragedy of death by suffocation.
Preferably, the length of described steel disc is 400mm, and width is 10mm, and thickness is 1.5mm.
Preferably, described passage is groove, and sonet card is connected in groove.Thus before use after the situation of observable optical fiber, to guarantee that optical fiber is all right before use, thus guarantee carrying out smoothly of visual intubate.
Preferably, described steel disc is spring steel plate.Spring steel good toughness, easily bends.
Preferably, described optical fiber slides and is arranged in groove.To facilitate the replacing of optical fiber.
Preferably, described optical fiber and groove matched in clearance, the degree of depth of groove is greater than the radius of optical fiber and is less than the diameter of optical fiber, and the notch of groove and the bottom of groove all offset with optical fiber.Thus realize the clamping of optical fiber and groove and be slidably connected.
Preferably, on described steel disc, radial direction is provided with one group of through hole.Through hole can reduce the power needed for bending steel disc.
